The ASRock Rack E3C256D4U-2L2T is a Micro-ATX server motherboard for Intel Xeon E-2300 or 10th Gen Pentium processors, suited to compact server builds that need dual 10GbE, IPMI remote management, and support for ECC or non-ECC UDIMM memory.
Recommended For
- Small-business and entry-level enterprise operators building a compact server for web hosting or general workloads who want out-of-band IPMI management without moving to a full-size platform.
- NAS and storage-server builders who need several SATA drives, M.2 storage, and onboard 10GbE for moving files across a fast local network.
- Homelab builders running a moderate number of server or virtualized workloads who value ECC UDIMM support and remote management, and can work within the board’s four-DIMM memory limit.
- Micro-ATX server builders who need two onboard 10GbE connections plus separate 1GbE ports for management or other network roles, rather than adding a 10GbE card.
Spec Summary
| Attribute | Value |
|---|
| Best For | Single-processor server builds using supported Intel Xeon E-2300 or 10th Gen Intel Pentium processors, with ECC or non-ECC UDIMM memory, multiple SATA and M.2 storage options, and IPMI management |
|---|
| Processor And Platform | Single Socket H5 (LGA1200) for one supported Intel Xeon E-2300 or 10th Gen Intel Pentium processor, on the Intel C256 chipset |
|---|
| Memory Configuration | Four DDR4 288-pin ECC or non-ECC UDIMM slots (2DPC), supporting up to 32GB per DIMM; maximum frequency is 3200MHz, or 2666MHz with a 10th Gen Intel Pentium processor |
|---|
| Expansion Slots | One PCIe 4.0 x16, one PCIe 4.0 x4, and one PCIe 3.0 x1 slot; with a 10th Gen Intel Pentium processor, the x16 slot operates at PCIe 3.0 and the x4 slot is unavailable |
|---|
| Storage And RAID | Eight SATA 6Gb/s ports with RAID 0/1/5/10, plus two M-key M.2 slots: one supports PCIe 3.0 x4 or SATA and 22110/2280/2260 drives, and the other supports PCIe 3.0 x4 and 2280/2260 drives; using a SATA device in M2_1 disables SATA0 |
|---|
| Networking And Management | Two Intel X710-AT2 10GbE RJ45 ports, two Intel i210 1GbE RJ45 ports, and a dedicated IPMI LAN port for remote management |
|---|
